    <p>Предложен новый подходк расчетувнутримолекулярного вкладаво второймомент линиипоглощения ЯМРдля кристаллов с внутренними заторможенными движениями, позволяющий предсказать в аналитической форме егозависимость оториентации кристалла во внешнеммагнитном поле. В качествемодели молекулярного движения использована модель расширенных угловых скачков. Справедливость теорииподтверждается экспериментальными данными повторому моментупротонов вмонокристалле хлоридааммония. </p>

    <p>A new approach to calculating the intramolecular contribution to the second moment of an absorption line of nuclear magnetic resonance for crystals with the internal hindered motion is suggested, allowing to predict in the analytical form its dependence on orientation of the crystal in an external magnetic field. The extended angular jump model is used as the molecular motion model. The theory is satisfactory applied to interpretation of the experimental second moment of protons in a single crystal of ammonium chloride. </p>
